Classical Nucleation Theory (CNT) is a theoretical framework used to describe the formation of new phase domains, such as droplets or crystals, in a system. This process, called nucleation, is essential in areas like materials science, atmospheric science, and the study of phase transitions. Here are the key components of Classical Nucleation Theory: 1. **Nucleation Basics**: Nucleation occurs when a new phase (e.g.
